Specialty Fibers : Photosensitive Fibers

For Bragg Grating

iXblue Photonics Photosensitive Single Mode Fibers have been designed to suppress the cladding modes losses (CMF Cladding Mode Free) or to adapt the cladding mode offset (CMS Cladding Mode Shifted) in order to optimize the channel spacing.

Photosensitive fibers exhibit uniform and controlled photosensitivity to conventional UV radiation techniques and are available in a wide range of photo-sensitivity levels.

 

Key features:

  • Hydrogen loading necessary
  • High thermal stability Grating
  • Double clad design for fiber laser cavity
